[PATCH] arm: PR 29739 Fix typo where ';' should not have been replaced with '@'

[Christophe Lyon <christophe.lyon@arm.com>]

';' does not always indicate the start of a comment, and commit
8cb6e17571f3fb66ccd4fa19f881602542cd06fc incorrectly replaced 3
instances of ';' with '@' in expected diagnostics, leading to tests
failures.

This patch restores the original ';' as needed in these testcases.
